Texas A&M AgriLife Research scientists published a study on bioenergy sorghum hybrids that shows they can capture and sequester significant amounts of atmospheric carbon dioxide in soil. Specifically, the study revealed that an acre planted with a bioenergy sorghum hybrid accumulates about 3.1 tons of dry root biomass. In addition, a press release notes that bioenergy sorghum's 6.5-feet deep root system can reach water and nutrients that other annual crops don't. Researchers suggest the crop can help manage fertilizer runoff from other annuals in a crop rotation....

A study by researchers from Rutgers University-New Brunswick and the University of Maine indicates that agricultural practices can help increase carbon storage in soils. Ecosystem Service Valuation Approaches and Carbon Mitigation Considerations for Garden State Agriculture says that cover cropping, grazing management, and agroforestry can increase the amount of carbon stored in agricultural soils and help New Jersey meet emissions reductions goals. In addition, these practices can help provide other ecosystem services, ranging from soil health to flood mitigation....

University of Wisconsin agronomy professor Randy Jackson has been exploring the potential for cropping systems to accumulate enough carbon in agricultural soils to help stabilize the climate, reports Agri-View. Jackson's 15 years of research have shown that all cropping systems studied, including crop rotations and organic rotations, lose carbon over time. Pasture systems were able to maintain carbon levels, but this reflected a small gain in the top 30 cm offset by losses below that level. "We're losing 25 grams of carbon per meter squared in the annual cropping systems when we need to be gaining between 10 and 70...

Related ATTRA Publication: Sustainable Cotton Production for the Humid South The Ralph Lauren Corporate Foundation and the Soil Health Institute announced the launch of Institute's U.S. Regenerative Cotton Fund (USRCF), a unique, farmer-facing, science-based initiative that will support long-term, sustainable cotton production in the United States, with the goal of eliminating one million metric tons of carbon dioxide equivalent from the atmosphere by 2026. Organizers say the USRCF will empower cotton farmers to adopt regenerative practices, like cover cropping and no till, in a way that benefits their operation. The Soil Health Institute will work closely with cotton farmers to help them...
